"Another angel came and stood at the altar, holding a gold censer. He was given a great quantity of incense to offer, along with the prayers of all the saints, on the gold altar that was before the throne.
The smoke of the incense along with the prayers of the saints went up before God from the hand of the angel."
Revelation 8:3-4
956 The intercession of the saints. "Being more closely united to Christ, those who dwell in heaven fix the whole Church more firmly in holiness. . . . They do not cease to intercede with the Father for us, as they proffer the merits which they acquired on earth through the one mediator between God and men, Christ Jesus . . . . So by their fraternal concern is our weakness greatly helped."495
I want to spend my heaven in doing good on earth.497
957 Communion with the saints. "It is not merely by the title of example that we cherish the memory of those in heaven; we seek, rather, that by this devotion to the exercise of fraternal charity the union of the whole Church in the Spirit may be strengthened. Exactly as Christian communion among our fellow pilgrims brings us closer to Christ, so our communion with the saints joins us to Christ, from whom as from its fountain and head issues all grace, and the life of the People of God itself"498:
958 Communion with the dead. "In full consciousness of this communion of the whole Mystical Body of Jesus Christ, the Church in its pilgrim members, from the very earliest days of the Christian religion, has honored with great respect the memory of the dead; and 'because it is a holy and a wholesome thought to pray for the dead that they may be loosed from their sins' she offers her suffrages for them."500 Our prayer for them is capable not only of helping them, but also of making their intercession for us effective.
959 In the one family of God. "For if we continue to love one another and to join in praising the Most Holy Trinity - all of us who are sons of God and form one family in Christ - we will be faithful to the deepest vocation of the Church."501
